This semester in VIS 2128 we explored multiple topics related to spatial analysis in R and R Studio. Over 7 weeks, we covered the modules listed below. The following work demonstrates the material of each module and its associated learnings to show the synthesis of skill-sets acquired throughout the course.
Modules Covered:
These two maps compare open space and park lights in Cambridge, MA. We selected these data layers to explore how well-lit the city’s open spaces and parks are and how that may contribute to a resident’s sense of safety and accessibility to those spaces at night. Skills used:
This map was created by georeferencing a historic map of Philadelphia from 1779 in ArcGIS. It documents the extent of impervious surfaces within the modern city as well as the locations of municipal stormwater outfalls (displayed as blue dots). It demonstrates the following skills:
This series of maps shows the relationship between bike crashes and different neighborhoods in Philadelphia. The first map aggregates the number of bike crashes in each Philadelphia neighborhood. The second map shows the density of bike crashes per square mile in each neighborhood. They demonstrate the following skills:
These maps demonstrate travel times to the nearest restaurants and cinemas in Providence, RI. Isochrones are used to show the area that can be reached within 5, 10, and 20 minute cutoff travel times. Both maps show travel time for biking or walking. Skills demonstrated:
These two maps show accessibility based on an exponential distance-decay function of the walking time to the nearest cinema and restaurant in Providence, RI. Both maps were converted from a polygon layer to a raster layer. They demonstrate the following skills:
These two maps were converted into a vector layer from a raster layer. They also display accessibility based on an exponential distance-decay function of the walking time to the nearest restaurant in Providence, RI. They show the number of restaurants a pedestrian can access by walking from a specific point. The second map displays this relationship using contours. Skills demonstrated:
This map shows the unit vacancy rate for Detroit Michigan in context to the greater Wayne County. It includes the total units, units occupied, and units vacant per census block parcel. The pop-ups indicate the percent of vacancy per block. The following skills are demonstrated:
